Answer:
x = 6
Explanation:
y = x - 4
26 = 4x + y
If y = y, then we can rewrite this system as this: 4x + x - 4 = 26
Then we combine like terms and add 4 on both sides to give us 5 x = 30
. Divide by 5 on both sides and we arrive at the solution: x = 6
Answer:
Step-by-step explanation:
We are told the school sold raffle tickets, and each ticket has a digit either 1, 2, or 3. The school also sold 2 tickets with the number 000.
Therefore we have the following raffle tickets:
123
132
213
231
312
321
000
000
From the given information, we can deduce that the school sold 8 tickets and only one ticket can contain the number arrangement of 123, but 000 appeared twice.
Probability of 123 to be picked=
1/8 => 0.125
Probability of 000 to be picked=
2/8 => 0.25
Since the probability of 000 to be picked is greater than 123, a ticket number of 000 is more likely to be picked

Answer:
C. 
Step-by-step explanation:
To find the value f b, we need to compare the exponents.
The given exponential equation is:
Recall and apply the following rule of exponents.
We apply this rule on both sides to get:
Simplify the exponents on the left.
Comparing exponents of the same variables on both sides,
Divide both sides by 6.
